source: flair-src/trunk/lib/FlairSimulator/src/Gui_impl.cpp@ 426

Last change on this file since 426 was 365, checked in by Sanahuja Guillaume, 4 years ago

change simu apps compilation to avoid problem with mixing host and toolchain libs
(log2@glibc_2.29 error when compiling on ubuntu 20.05 or mint 20)
now compile with host g++ and libs (except filelib, irrlicht, quat, udt and vrpn) for simu apps using the macro: FLAIR_DEMO_HOST_CXX
